A Comparative Study of Compression Video Technology.
Keller, Chris A.; And Others
The purpose of this study was to provide an overview of compression devices used to increase the cost effectiveness of teleconferences by reducing satellite bandwidth requirements for the transmission of television pictures and accompanying audio signals. The main body of the report describes the comparison study of compression rates and their effects on video quality using a common source tape of color graphics, teleconference scenes, and motion footage. The remaining sections of the report describe the equipment tested, equipment configurations, actual bench and field test results, current academic applications using compression technology, and equipment prices and features.
